Katherine says motherhood has given her perspective

The 'Doubt' actress, who has two adopted daughters, Naleigh, six, and Adalaide, three, with husband Josh Kelley, says they forced her to take a step back and realise there is more to life than acting.

She said: "It's been a huge blessing - it gave me perspective. Before them, it was all about my goals as an actor. They helped me to take a step back and go, OK, I have some important work to do on this earth.

"Naleigh is six going on 13! She's very sassy and confident. Adalaide's a total tomboy who's obsessed with bugs. The other day she was digging for worms."

The blonde beauty thinks her musician husband is a "fantastic" father.

She told InTouch: "He get sup with them in the morning more often than me. I am not a morning person. The girls are obsessed with him. I think that every woman with healthy self-esteem had a really great dad."

The couple relocated to Utah from Los Angeles to raise their daughters away from the spotlight in 2010.

Katherine explained: "We live in a small ranching town 7,000 feet up in the mountains. It's so peaceful."
